BMW S1000RR Valves at Full RPM | Video

Titanium Valves Video

This rare technical video of the new BMW S 1000 RR Superbike, showing valves operating at a very high RPM, is a must see for any motoring enthusiast.

The water-cooled four-cylinder inline power unit develops a maximum claimed output of 142 kW (193 hp) at 13,000 rpm and revving up to a maximum speed of 14,200 rpm. Maximum torque of 112 Nm (82.5 lb-ft), in turn, comes at 9,750 rpm.

The two intake and exhaust valves per cylinder made of extra-light titanium are operated by very small and equally light single cam followers.

In conjunction with the short sprocket driving the camshaft via an intermediate gear, this ensures supreme revving qualities at the highest speeds as well as exact maintenance of valve timing combined with very compact dimensions.

The use of extremely small and light cam followers furthermore gives the engineer greater freedom in choosing the ideal valve lift curves and, accordingly, in selecting optimum performance characteristics on both road and track.

All engine components are particularly compact and light, limiting weight of the overall engine without ancillaries to 59.8 kg (131.8 lb) and keeping the entire power unit very slim and slender.
